Dear customer, thank you for choosing Justanswer. My name is***** would like to help you.

Is there a warning light in the speedometer?
Describe exactly what the problem is, how it feels, how it is noticed, etc.

Hi thanks for getting back too me no no warning lights.its just when im stationary i can feel a slight judder like a misfire and vibration and you can hear it as the exhaust note changes if that makes sense
Expert:  experteer replied 7 months ago.

I wouldn't tie that to the exhaust. The exhaust pipes have internal membranes for a sporty sound. The sound changes when I warm up.

But if you feel a slight shaking it can be a hiwneis for occasional misfires, I would start with the spark plugs, check them visually and change them if necessary. Sometimes the ignition coils are also defective and do not ignite the engine well.

I would be very happy about a rating with 5 stars over the star bar at the top of the page, without this rating the site operator does not pay us experts.

Would a vacuum leak cause these symptoms? Ive changed the spark plugs recently
Expert:  experteer replied 7 months ago.

Yes that`s possible.

Customer: replied 7 months ago.
how do i test for this please?
Expert:  experteer replied 7 months ago.

There are leak detection sprays for engines with which you can spray the intake trunking while the engine is running. If there is a leak, the engine starts to jolt strongly.

Do you know much about the piston 4 issue with the corsa vxr's
Expert:  experteer replied 7 months ago.

That's not the case with your car.

If the piston had a hole, the oil level would rise, because fuel would come into the oil pan, a mixture of oil and fuel would come out of the exhaust and the car would only run on 3 cylinders. or however variant two, if the connecting rod breaks, the piston would come out of the engine with a loud bang. Both would have completely different symptoms.

Ok i ran a compression test on my vehicle and results were 160 psi across all 4 cylinders but im still getting a missing sound when warm
Expert:  experteer replied 7 months ago.

You could have saved yourself the compression test. As I said in my last answer, the problem with cylinder 4 is excluded.

What came out of the test for leaks in the intake system?

Customer: replied 7 months ago.
I havent done that yet can you please can you tell me how to do this you said spray it into my air intake system yes?another thing that i thought of was that when i installed the new plugs i didnt check the gap when installing them
Expert:  experteer replied 7 months ago.

No, not in the intake tract, just while the engine is running on the outside.

Customer: replied 7 months ago.
Ive changed my intake pipe to a solid metal intake pipe
Customer: replied 7 months ago.
